This invention relates to driving means for sleeve valves or the like, and more par ticularly, to driving means for rotating sleeve valves of the type used in internal combustion motors.

Ina sleeve valve of this type it-has been generally customary to rotate the sleeve valve by means of a separate gear ring which is connected to the sleeve valve by means of a jaw clutch. This method of connection necessitates extreme accuracy in manufacture, since for proper working, the valve and gear rm ment. I exact alignment does not ex st, a the gear and valve will revolve eccentrically and the consequent gyration of both the gear and valve will necessitate an excessive amount of clearance between the valve and member in contact with which it rotates. Such an vexcessive clearance revents the valve from functioning proper y since gas leakage is facilitated and it IS impossible to 7 properly control the flow and distribution of ubricant.

It'is an object of the present invention I to rovide connection of this character, in

which the valve shall ;be radially independ-' ent of the driving gear.

i It is. a further object to provide construe: a0 tlon in which the valve and drive ring may move radially relative to 'each other during their rotation without strain upon the drivmg connection.

It is an additional object to provide a 86 construction of this character which is sim ple in design and is adapted for commercial production and operation Other and further objects will appear as the description proceeds.

I have i lustrated a preferred embodiment 1n the accompanying di'awings, in which IfIgure 1 is a vertical section of an engine cylinder with my invention applied thereto; Figure 2 is an elevation of the sleeve. valve, coupling member and drive ring, and Figure 3 is a plan view of the drive ring. A sleeve valve engine has been shown somewhat diagrammatically in Figure 1 and comprises the cylinder block 11, crank case 12, cylinder head 13, crank shaft14, connectmg-rod and piston 16. The piston reciprocates in the inner cylinder member. 17 whichjs retained in' the cylinder block I]? Themner cylinder member is must be in perfect axial alignwith a'port 18 in registration with a similar port in the cylinder block.

The sleeve valve 19 is fitted between the cylinder block 11 and inner cylinder memformed on the upper surface of the gear ring 23. The lateral faces 31 of these jaws engage similar 'surfaces 32 formed on the coupling member. It will-be noted from Figure 3 that the surfaces 27'and 32, are formed substantially at right'angls to each other.

It will be understood that in the operation of the'engine thegear ring 23 is continuously rotated by the worm 25. This 22 is recessed at 29 to receive the jaws 30 rotation is transmitted by the meeting jaws to the coupling member 22 and thence tothe sleeve valve 19. It will be apparent that the meeting jaws between the geanring and coupling and coupling and sleevevalve being at right angles to each. other will permit eccentricity of the sleeve valve and gear ring withoutstrain upon the driving connection. The sleeve valve may thus make a gas and oil tight fit with the cylinder block and inner cylinder without the necessity for having the gear ring machined and fitted absolutely concentric with the sleeve valve. It will be understood that the usual eccentricity will be a very minute fraction of an inch and it ,has been considerably exaggerated in the drawings for the'sake of clearness.

I have. shown one preferred form of construction by way of example only and 'contemplate suchv changes and modifications as I claim 1. In a sleeve valve construct1on, .a sleeve valve,a drlve member, anda couplmg memcome within the spirit and scopeof the accompanying claims.
